Valuing the catch: economics at the margins of the data
Fisheries economics operates where data is sparse and stakes are high. We discuss how to build defensible evidence under genuine uncertainty.
Few sectors test the economist's craft like fisheries. The underlying resource is uncertain, the data is incomplete, and the decisions at stake — quotas, access, investment — carry significant economic and social consequences for coastal communities.
Working at the margins of the data demands a particular analytical posture. The temptation to over-claim precision must be resisted; equally, the absence of perfect data is not a reason to withhold evidence. The task is to be rigorous about what can and cannot be concluded.
In our experience, the most useful fisheries analysis combines several imperfect sources — landings data, market prices, effort measures — and is explicit about how they have been reconciled. Triangulation across sources, with clearly stated assumptions, produces evidence that is both useful and honest.
The result is not certainty, which is unavailable, but a structured and transparent account of the economics — one that decision-makers can weigh alongside the social and environmental considerations that fisheries policy must balance.
